I've learned a lot since originally making these and very much want to do them to current standards. In addition to replacing the F39/a/c cars previously done (working from much better drawings this time!), I've collected a reasonable amount of material towards the cast F39B cars, as well as some of those owned by the Erie and later stretched 10 feet by EL. I now have sufficient information to do ATTX cars in non-TOFC service for the 70s and 80s, and the odd handful of photos of cars owned by other roads.
Long story short, these are very cool cars and I certainly have plans to do them justice with a new model. I don't believe there's anywhere the originals are available for download, nor to my knowledge do I still have copies easily accessible. The cost of progress I suppose...
